Product Description
DF,MD,DY,D series self-balancing horizontal multistage centrifugal pump, divided into single suction multistage structure and double suction multistage structure.The typical characteristics of this type of pump in the structure of the balance disk system completely cancel the balance of axial force, using the impeller symmetrical automatic distribution balance axial force, this innovation makes the multistage pump in operation with high efficiency and energy saving, stable and reliable, less wear, reduce costs and other advantages
Pump inlet pressure is not more than 0.6mpa.
Model significance:
